CVE-2026-98572
Description
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix immediate JMP JEQ/JNE on MIPS32
An addu instruction was emitted instead of addiu, causing the immediate value 1 to be interpreted as register $at. This made the comparison result invalid when the immediate operand was negative. Note that $at is mapped to BPF_REG_AX, which is used for constant blinding.
Fix the instruction to use the immediate form.
Found with test_bpf on MIPS32r1 emulated by QEMU.
